IMPnovEMENT IN wARPiNe-MACHINES.

The Scheule referred to in these Letters Patent anmaking part of the same.

I, THOMAS SINGLETON, of Over Darwen, in the county of Lancaster, England, have invented certain Improvements in arping-Machines,.1 of which the following is a specification.

Nat/zere and Oly'ects of the Intention.

The nature of my invention consists' in a self-acting stopping motion, and has for its object that of causing the machine to stop in case a thread of the warp breaks.

For this purpose I take an ordinary warping-machine and place near where the warp passes through the front comb, either in front or behind the said comb, two or more bars or plates of metal or other material placed edge upward and extending across the machine.` These bars or plates may he attached together at the ends orrest separately in suitable bearings, the said bars and the spaces between them forming a sort of grid or grate, which, instead of being made in parts as here describechmay be made in one piece.

The said grid or grate Idplace in such a position that the threads of the warp shall Vpass across the spaces in the. grid and touch, or nearly so, the metal between the spaces.

Upon each thread of the warp I hang a small.

weight, by preference in the formof a staple, open at ornear the bottom, for the convenience oi' putting it on the thread. These staples hang down in the spaces of the grid, the metal barsof which serve to keep them from. moving forward or backwardwith the threads of the warp upon which they hang, at the same time the slots or spaces in the grid will allow them to move sidewise as the sheet 'of'warp may be expanded or contracted in width.

Extending allalong, and just below where these staples hang upon the threads of the warp, I ,have two rollers, either iiuted or plain, revolving in 'contact, one only o f which rollers need be driven by the machine, asthe other roller, being fre-e to turn, will revolve by contact with the driven roller.

One of the two rollers, which I will call the swingroller, is suspended by two arms, and is capable of moving to andV from the other roller. lhe said varms are either each attached to a shaft, so that one arm may not more without the other, or they may be attached to the grid, which, in that `caseris made with a pivot at each end, so that it may turn slightly.

-If a thread of the warp should break, the :staple hung upon it at once falls down onto and is taken be. tween the two rollers revolving below, thus separating them a short distance apart, and causing' a pin or projection on one of the arms to push the ordinary knockingott spring from its detent, and so stop the machine.

rI he operative `has a number of spare staples, and, after pieciug the broken thread, drops one of them upon it to replace the one that yhas passed through the rollers. Those which pass through the rollers fall into a boxv below them, from which box they may be taken out occasionally.

Description of the Accompanying Drawing.

Figure l is au end elevation of a machine embodying my invention.

Figure 2 is a transverse section.

Figure 3 is a part ot a front elevation.

Figures 4 and 5 are detached parts, showing the arms attached to the grid, and showing the pivots lot' the grid.

Figures G and 7 show the staples fullsize.

General Descrptz'mn A is theft-ame of the machine;

D, the beam upon which the warp is wound; and

C, the threads of the warp coming to the machine from the creel, and which, after passing` under and over the various rollers, pass through the staples E E E on their way to the beam. v

D D D D are the bars ot' metal forming the grid.' F and G are the two rollers revolving in contact, F being the driven one, and receiving itsl motion from the driving-shaft H of the machine either by means of an arrangement of toothed gearing, as shown by the parts I J K L M, or by means of a pulley on the shaft H driving a pulley on the roller F' by a strap.

` Gris the roller which revolves by contact with the roller F. It is supported by arms N, gs. 1, 2,3, or by arms P, gs. 4 and 5.

The arms N are attached to the shaft Q, iigs.'2 and. 3, for the purpose of insuring them both moving at once.

Figs. 4 anti 5 show the manner of attaching the arms to the grid in lieu of to the shaft Q,vin which case the grid is made with a journal, R, to allow it to adapt itself to the mo'tiou of the arms.

S is au adjustable pin or projection upon one of the arms, and acts upon the knocking-ofi` springfl, pressing it out of its detent in the bracket U, when, as is usual, the spring fries inward and carries with it the rod V, to which is attached the strap-fork, and which carries the strap onto the loose pulley, andthe machine stops.

W XV are pieces of fianuel resting lightly on th two rollers, and serving to keep them clean. A

X is the box intovwhich the staples fall aftsl' passbuaton with the rollers F and G, to stop the maing through the rollers. chine, as herenbefore described. Y
